The screenshots in this tutorial may appear to be different from the
version of Irfanview that you download. But the rules are the same.

For the sake of this tutorial, please make a folder on your DESKTOP
Name it: pictures

Put the photo you want to resize into the "pictures" folder on
your desktop. I am
using an image called SceneWater.jpg.
You may download it from here if you'd like to use the same photo while
practicing this resizing exercise.

Double click the Irfanview icon on your desktop to open the photo program. The icon looks
like this:

STEP ONE
With your mouse, left click on FILE on
the menu bar, continue holding your left button down and drag your cursor down to
OPEN

STEP TWO
A window (as above) will open. Go to your "pictures" folder on your
desktop and you should see the image you're going to resize .. in the
example above is the SceneWater.jpg. Left click on it once to select it,
then click the OPEN button.

STEP THREE
To determine the size of your image, left click on
IMAGE on the menu bar and drag your
mouse down to RESIZE/RESAMPLE

STEP FOUR
If using the image SceneWater.jpg, you will see the width is 720 pixels,
the height is 577 pixels and the DPI (dots per inch) is 72. Too
big!! That translates into 10 x 8 inches (there are 72 pixels per inch).
We need to reduce the physical size of the image. The 72 dpi is
fine. Make sure the PRESERVE ASPECT RATIO box has a check mark in
it.

STEP FIVE
Erase (select and delete) the 720 in the WIDTH box and type 432. 432
translates to 6 inches. (remember -- 72 pixels = 1 inch).
Because you have the PRESERVE ASPECT RATIO checked, the width will
automatically change to 346 (4.8 inches). If you have any number
other than 72 in the DPI window, (e.g. 300, 150) change it now by erasing
your number and typing 72. Click OK.

STEP SIX
Now you need to 'save' your image with its new size. On the menu
bar, left click on FILE, drag your mouse down to
SAVE AS. (If you simply
click SAVE, you will override your original image, which you might not
want to do. I always keep my original images.)

A window will open. Make sure you're saving your new image in your
'pictures' folder on your desktop so you don't lose it. Browse to
your desktop/pictures if it doesn't
automatically come up in the LOOK IN:
location bar at the top of this window. Give your new image a new
name -- I have called it Mountains. Type this new name in the
FILE NAME: window. SAVE AS TYPE: drop menu down and drag
your mouse down to JPG - JPEG Files to
select the .jpg option.
Click the SAVE button.

You now have a new image, called Mountains.jpg, 432 x 346 pixels (6" x
4.8") at 72 dpi. A much more manageable image size to send your
friends via email.

If you'd like to take this one step further, here are instructions for
CROPPING your image.

With your newly resized image open, LEFT click on the image to determine
the top left corner of where you'd like to
begin your cropping and holding your left mouse button down, drag over your
image to the right and in a downward motion till you 'select' the area you'd like to KEEP. If it doesn't
work right the first time, left click on it again, and drag again until
you're happy with the area you'd like to save. I've selected the
'main' part of the photo above and am eliminating some of the sky and some
of the black section at the bottom of the image.

Now go to EDIT, drag your mouse down to
Crop selection and let go of
your mouse button.

Our newly cropped and resized photo.
You need to save it again because you have made changes to the image since
your last save. So click on FILE then drag your mouse down to
SAVE
(name will remain as Mountains.jpg), click SAVE.
